Neglected White-toothed Shrew
Crocidura neglecta
French:
Crocidure de Sumatra
/
German:
Vergessene WeilRzahnspitzmaus
/
Spanish:
Musarafna descuidada
Other common names:
Sumatran White-toothed Shrew
Taxonomy.
Crocidura neglecta Jentink, 1888
,
“
Sumatra
,”
Indonesia
.
Formerly grouped with other small Cro- cdura (e.g.
C. monticola
or
C. maxi
) of Sundaland, but recent phylogenetic reconstructions based on mtDNA and multiple nDNA genes show that they are only distant relatives; these molecular data place
neglecta
in a distinct clade that is more closely related to Indochinese
C. attenuata
; this clade comprises other small
shrews of uncertain taxonomic status from Borneo and Peninsular Malaysia and variously reported as C.
cf. monticola
, C.
cf. maxi
or
C. cf. neglecta
; they differ by less than 4% sequence divergence at the cytochrome-b gene from Sumatran
C. neglecta
and may therefore prove conspecific with it. Monotypic.
Distribution.
Known definitely from two areas in N &W Sumatra (Mt Tujuh and Bukit Lawan), but if morphologically and genetically similar specimens from Borneo and Peninsular Malaysia prove to be conspecifics, its distribution might be more extensive across the Sundaland.
Descriptive notes.
Head—body 54-55 mm, tail 34-41 mm, ear 7-8 mm, hindfoot 9-8— 10-2 mm. No specific data are available for body weight. Small-bodied shrew with dark pelage, dorsal hairs tipped with brownish red, underparts somewhatlighter. Hairy feet. Relatively short, hairy, cylindrical tail, with long bristle hairs along its proximal 10 mm.
Habitat.
Primary and secondary rainforest. Altitudinal range 160-1600 m.
Food and Feeding.
Feeds on invertebrates but no precise data are available.

Status and Conservation.
Not assessed on The IUCN Red List as a separate species from the Sunda White-toothed Shrew (
C. monticola
), which is classified as Least Concern. Thought to be not threatened because of its supposedly widespread occurrence in the Sundaland. Owing to revised taxonomy, now restricted to northern Sumatra and may be under threat by ongoing destruction ofits forest habitats. It is, however, present in at least two large protected areas (Gunung Leuser and Kerinci-Seblat national parks) but population densities and trends are unknown. Collection of additional specimens is needed to clarify the taxonomic position of similar, small-bodied
Crocidura
from Borneo and Peninsular Malaysia. If they prove conspecific, the current range of
C. neglecta
would be considerably more extensive.
